Mirage M1 big bipolar speakers in small room

Have Mirage M3s and agree with George.

In that room, I’d suggest setting up your Mirages along a diagonal (like you room is a diamond instead of a square). This will geometrically delay the arrival of the first reflections. If the reflections from the rear-firing drivers arrives too soon, they will degrade clarity. But delay their arrival for long enough (10 milliseconds is a good target) and they will enhance timbre and envelopment with little or no degradation of clarity... in fact you may even find that clarity is improved.

Great speaker, but they need a lot of room behind them to sound their best, at least 2mts, and >1mt from the sides.
Cheers George
